Organic diradicaloids have unusual open-shell nature and properties and are promising
materials for organic electronics, spintronics, energy storage and nonlinear optics. In this …

Inclusion of quinoidal cores in conjugated hydrocarbons is a common strategy to modulate
the properties of diradicaloids formed by aromaticity recovery within the quinoidal unit. Here …

The preparation of a series of dibenzo-and tetrabenzo-fused fluoreno [3, 2-b] fluorenes is
disclosed, and the diradicaloid properties of these molecules are compared with those of a …

A direct, efficient and versatile strategy for the modulation of optoelectronic and magnetic
properties of indeno [1, 2-b] fluorene has been developed. 4-Substituted-2, 6 …

This mini-review highlights key structural features that should be taken into account when
creating ambipolar redox-active closed-shell metal-free molecules. This type of compound is …

Quinoidal azaacenes with almost pure diradical character (y= 0.95 to y= 0.99) were
synthesized. All compounds exhibit paramagnetic behavior investigated by EPR and NMR …

Biradicaloid compounds with an open-shell ground state have been the subject of intense
research in the past decade. Although diindenoacenes are one of the most developed …

The ability to alter optoelectronic and magnetic properties of molecules at a late stage in
their preparation is in general a nontrivial feat. Here, we report the late-stage oxidation of …

A new diradical based on diindenocarbazole or difluorenopyrrole was synthesized and
experimentally characterized by optical, electrochemical, and magnetic techniques, as well …

The singlet open‐shell character and antiaromaticity are intriguing features in π‐conjugated
carbocycles. These two exhibit similar chemical and physical properties. However, they …
